Many visitors to Basel get around on foot, as the old city is fairly compact and many streets have been pedestrianised, with recommended colour-coded walking routes for tourists. Some parts of the city have steep inclines, however, so walking tours are only recommended for the moderately fit. Bicycles are also a common sight in Basel, and are available for hire.Basel has an extensive bus and tram network, which is easy and convenient to use. Tickets are sold from machines at stops and stations. Single tickets start at CHF 2.30, and day passes are available.All the pedestrians, trams, buses and bicycles add up to a city that can be confusing to drive in. Parking is scarce in Basel, although there are public garages available. Hiring a car is therefore only recommended for excursions out of the city.
